Hi,

While I try to work with sample code to test the algorithm that you have wrotten, I got this below error;

Traceback (most recent call last):
  File "gas.py", line 16, in <module>
    client.read_parameters([IFlagParameter(id=0x5e, data_class=CorusString)])
  File "/usr/local/lib/python3.6/dist-packages/iflag/client.py", line 70, in read_parameters
    in_data = self._read_parameters_by_id(parameter_ids)
  File "/usr/local/lib/python3.6/dist-packages/iflag/client.py", line 252, in _read_parameters_by_id
    self.transport.send(msg.to_bytes())
  File "/usr/local/lib/python3.6/dist-packages/iflag/transport.py", line 67, in send
    self._send(data)
  File "/usr/local/lib/python3.6/dist-packages/iflag/transport.py", line 132, in _send
    self.socket.sendall(data)
AttributeError: 'TcpTransport' object has no attribute 'socket'

Please give some tips :)

The attribute for socket is set on connect() which is not very nice structure. An Optional socket variable should be set on init. Probably just a miss since there is typing for the socket in init

relates to #6

In newer version of i-flag the paramteres have been extendend and now include numbers that are not representable with one byte.

The second byte is padded with 1:s on the left half of the byte.

Ex: 284 -> 0x100 -> b"\xf1\x20"

Need to investigate when the initial values is padded with \xf0. It could be when the first byte contains 4 1:s in the left half. so that it is not confused with the start of a 2 byte parameter.

After creating a client you need to call .startup() to init the connection and send wakeup procedure etc.

Relate to: #6

IFlag when running prevents SRS Studio software from recognizing tachometer and LED. Please resolve conflict so IFlag can run concurrently with SRS Studio which controls my StImulator. Thanks!
